To all whom it may concern:

Be it known that I LEROY R. MABEE, a citizen of the United States, residing at Hailey, in the county of Blaine, State of Idaho, have invented certain new and useful Improvements in Fuel Mixers for Gasoline Engines; and I do hereby declare the following to be' al full, clear, and exact description of the invention, such as will enable others skilled in the art to which. it appertains to make and use the same.

This invention relates to new and usefuln improvements in mixing devices and particularly to devices for mixing air and gas in the explosive charges lof gasoline engines.

One object of the invention is to construct a device of this character by means of which the air and gas which'passes from the carburetor to the intake manifold of the engine will be given a whirling motion with the result that the air and gas will be more intimately mixed before entering the cylinder of the engine.

Another object is to provide a device by means of which the air and gas charge, as it leaves the carburetor, will be .divided into two or more separate and whirling streams, each turning in a direction opposite to the other, and being across the path of the other, as the streams enter the intake manifold, with the result that a mixture'will be produced which will increase the power of thc engine, 'cause the thorough burning of the gas, with the elimination of carbon collections, and the smoother running of the engine. v l

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing: y Figure 1 is an enlarged elevation of the mixing device attached between the carburetor andintakeJ manifold of an automobile engine, the casing of the mixer being partly broken away to disclose the spiral fins or ribs. c, v i

Figure 2. is an end view of the device as seen from within the intake manifold.

AFigure 8 is a longitudinal central sectional view through the device. Figure L.his a central transverse sectional view through the device.

Various 'devices have been produced for causing the mixture of the air and gas as and air, at the inner end of they enter the intake manifold of gasoline opposite directions, but the greatdifliculty in such devices has been that the air and gas has been delivered in streams which consist of strata of air and gas unmixed. It is the principal object of the present invention to produce a device whereby the air and gas, as well as the semi-mixed air and gas is divided into several streams which are set into a whirling motion in opposite directions and cross each others path, with the result that a perfect and intimate mixture will be produced.

The above result`is accomplished by the structure shown in the accompanying drawing, wherein 10 represents an outer tubular' casing extending partly into the upper end of the carburetor 1'1, and partly into the intake manifold 12. Disposed concentrically within the casing 10 is a smaller tubular member 13, and centrally within the member 13' is a stem or postlfi. Secured attheir opposite edges to the inner face of the casing 10 and to the outer face of lthe member 13, and extending spirally therewithin, are the ribs' or ns 15, said ribs being arranged to discharge the gas Jshe device, and within the intake manifold. in a whirl toward the center of the manifold. Arranged between the center post 14, and the inner tube 13, with their opposite edges secured to the said post and to the inner face of the wall of thetube 13, are the spirally extending ribs 16, said ribs extending in a direction opposite to that of the ribs 15, so as to discharge the gas, into the intake manifold, toward thev outer wall thereof,

and across the path of the stream dis-` charged by the ribs 15, this stream being also given a whirling' motion by the spiral trend of the ribs 16. There are thus two streams of air and gas discharged into the intake manifold, concentric to each other, and directed across each others path, with the result that each stream will be thrown into and through the'other stream, andthe mixture, and breaking up of the air and gas particles made complete.

It will be' noted that there are no moving parts, or rotating fans in the present device, the charge of air and gas being drawn into the manifold by the suction of the engine.- and the whirling action produced automatically by the passage of the air and gas between the spirally arranged ribs. The present device is thus clearly distinguished from devices heretofore, bythe stationary ribs, which produce aresult attempted by others, but which has not been accomplished by them.

While I have described the devices as disposed between the carburetor and the in# take manifold, it will be understood that the same may be disposed at some point in the manifold, or may be built in the carburetor, or other place desired within the scope of the invention.

It will be further noted that each stream of gas passing through the device passes through a Venturi tube, each portion of the device being in effect such a Venturi. This also increases the speed of the streams of gasand the resultant mixed final stream,

In testimony whereof, I affix my signature, in the presence of two witnesses.
